a) Assume that you are going to a Galapagos Island to measure natural selection on morphology in a ground finch (Geospiza fortis). You suspect that some morphological traits will determine whether the individual bird survives or dies in the upcoming dry spell (drought). Is it a good research strategy to measure as many body traits as possible (wing length, leg length, body weight, tail length, etc.) or should a wise researcher just “bet” on a certain trait (for example, wing length) to be the key trait for surviving the drought? Why or why not?
